A beautiful Citigroup analyst jumped to her death in an apparent suicide yesterday from the roof of a ritzy Upper West Side high-rise, police said.

Jessica Fashano, 27, plunged from the crest of swanky Trump Place, which rises 40 stories above Riverside Boulevard, and landed face down in a third-floor courtyard just after 8 a.m., police and witnesses said.

“It was so loud I thought part of the building was falling,” a witness said.

Fashano, who cops said had sneaked into the building, landed a job as a Citigroup analyst after graduating from Georgetown University in 2005. The company even features the smiling brunette in a recruitment video.

Fashano, whose motive for jumping was unclear, also was active in charity work. In 2008, she teamed with other analysts to raise $189,260 for needy New Yorkers.
